Specification. of Letters Patent.

Toall who-m 'it may concern:

Be it known that I, Vieron E. EDWARDS, a

citizen of the United States, residing at Worcester, in the county of lVorcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Guides for Rolling-Mills', of which the following is a specification containing a full and clear description of my improved guide and accompanied by drawings illustrating the construction of the guide and its application to the consecutive rolls of a rolling mill.

` tion comprises a trough or conveyer by which the metal is conducted from one pair of rolls to the next consecutive pair; a delivery guide for delivering the metal from the first pair of rolls to the trough or conveyer and a receiving guide at the opposite end of the trough orconveyer by which the metal is received and brought into alineinent with the pass of the second pair of rolls.

The object of my invention is to simplify the construction in devices of this class and especially to obviate the liability of breakage due to an interruption in the movement of the metal from one pair of rolls to the other, and to this end my invention consists in certain novel. features of construction and arrangement of parts as hereinafter described and set forth in the annexed claims.

In the drawings accompanying this specification and forming a part thereof, Figure 1 represents a plan view of a guide by which metal is conducted from one pair of rolls in a rolling mill to the next consecutive pair of rolls. Fig. 2 is avdetached and plan view of the delivery guide box with the stripping p lates re1noved.` Fig. 3 is a transverse sectional view of the trough or conveyor. F ig. 4 is a detached and plan view of the receiving guide box with the cover removed in order to disclose the laterally adjustable check-plates by which the met al is brought into alineinent .with the pass in the second pair of rolls, and Flg. 5 isa central vertical sectional view of n. rolling mill guide embodying my invention.

cal si Similar referencevletters and iiffures refer nected with the pass D in the second pair of rolls B, B", by means of a guide embodying my present invention, having its opposite ends su ported by horizontal shelves E and F attac ed to the roll housings A and B respectively.

Supported upon the shelf E is a uide box 1 'com rising a bottom 2 and para lel verticies 3, 3, which are o en at the to The uide box 1 is attached) to the shelf il; by a olt 4. The under side of the bottom 2 is provided with a transverse shoulder 5 and the shelf E has a similar transverse shoulder 6. Between the shoulders 5 and 6 are inserted wedges 7, 7, by which the o'uide box 1 is adjusted on the shelf E relatiyeily to i the rolls A1, A2, the bolt 4 assing through the slot 8 in the bottom of t e uide box to permit such adjustment. The ottoni 2 of the guide box is also provided on its upper surface with shoulders 9 against which the rear end of the lower stripping plate 10 bears. The upper surface of the bottom 2 beneath the stripping plate 10 is slightly inclined at 11 to enable the stripping plate 10 to be supported at its rear end upon the bottom 2 and at its forward end by the periphery of the roll A.

Frictionally held between the sides 3, 3, of the guide box is a block 12 having one end bearing against one of the sides 3, and its opposite end receiving the pressure of a set screw 13. The block 12 is provided with a pair of projecting pins 14 beneath which is inserted the rear end of the upper stripping plate 15. The rear end of tie stripping late 15 bears against the block 12, and the forward end is brought into cont-actwith the periphery of .the roll A by the lateral adjustment of the block 12 in the guide bo The adjustment of the stripping plates .10 and 15 is accomplished by p i strip )ing plate 10 in position with its rear end earing against the shouldeis 9 and forcing the box 1 forward by the wedges 7,

icing the lower' .nunca-.z ff. eac/wss.

- ing against the periphery of the pass, serves sides o'.' the box 19 by bolts 26, and their to restrain the movement of the metal as the metal into alinement with the plate is brought into proper position against 'pass of the rolls B, B2. As each of the the periphery of the rol A, and the upper strip ing plate 15 is brought into proper position bythe adjustment of theblock 12e etween the sides 3 of the guide box, the desired space between the stripping plates 10 and .15.being determined bythe temporary insert-ion of a piece` of metal of the desired thickness of the metal rolled between the rolls A1, A. The upper stri ping late 15 is sus ended between the rollls an lille block 12 rom a rod 1'6 held in the housing A by means of a spiral spring 17, by which an upward pull is exerted upon thestripping p ate 15 to hold its forward end in cont-act with the peri hery of the roll A1. By -the above described method of holding the stripping plates 10 and 15, the above plates are easily removable and any interruption i-n the process of rolling which causes anaccumulation of metal in the guide box will serve to knock out the upper stripping plate and block 12 as the latter is held y frlction only, thereby causing an accumulation of metal to free itself. The free ends of the stripping plates 10 and 15 are concaved on the side next the rolls toform thin edges which, restto strip the metal from the roll.

The metal, after passing the rolls A, AE, is forced between the stripping plates 10 and 15 alid through the guide box 1 into a conveyer trough 13, and from the conveyer trough18 it is receivedinto a receiving guide box 19, which rests 1i on the horizontal shelfF and is attached tiereto by a bolt 20, said bolt passing through a slot 21 to allow the'box to e adjusted on the shelf F toward and away from the rolls B', B2. Depending lugs on the box -19 are provided with set screws 22, 22 by 'which the position of the box on the shelf F is determined. The receiving guide box 19 consists of a bottom 23 and a pair of vertical sides 24, 24, which are o en at the top, .and between which are' hel a pair of adjustable cheek-plates 25, 25. The cheekplates 25 are attached near one end to the free ends are crowded toward each other by a pair of wedges 27 which may be drivendown in slots 28 formed in the sides 24, until the free ends approach each other sufficiently it passes between them and guide it into the cheek-plates is independently adjustable their lateral position may be varied to bring etween the rolls. The bottom Z3 o the receiving guide box is recessed to receive a removable bottom piece 29 which supports the greater portion of the cheek-plates 25. Supported upon the upper edges of the cheekplates 25 is a cover 30 which is compressed against the cheek-plates by means of a Vdxvi. .x

wedge 31" actin against a' transverse plate 32 having its en s held in slots 33 in the sides 24 of the guide box 19.

At or near the receiving end of the conveye'rtrough 18 an opening 34 is provided in the bottom of the trough, which is covered fby a swinging plate 35,hinged upon a rod 36 held in the delivery,r` guide box. 1. to the under side of the plate 35 is a bracket 37 pivotally connected by a link 38 with an arm 39, carried on a rocking shaft 40, to which a lever 41 is attached, which serves as ahandle by which the shaft 40 may be rocked for the pur ose of lifting the plate 35 into the position s own by broken lines 42. The conveyer trough 18 has one of its ends resting upon the bottom 23 of the receiving guide box 19, and having its sides at the o posite end resting upon the rod 36lield in tllie delivery guide box 1. The function of the swinging plate 35 is to raise the 'moving metal as it passes through the conveyer trough 18 to allow it to form a loop above the eonveyer trough and thereby provide for an overfeed of metal between the consecutive pairs of rolls, and to accomplish this purpose the swinging plate 35 is placed at the initial end of the conve Yer trough and in close roximity to the delivery guide box l an( strip ing plates 10 and 15, in order that the meta may be dellectcd from a direct paththrough the conveyer trough at the initial end of'its support between the successive pairs of rolls, in order that a maximum length of the rolled metal may be taken up bj: the loop with a minimum elevation of the deflecting plate 35; the entire space between the two guide boxes being thereby practically available for the formation of the loop as indicated by the broken line 43 which shows the Attached the position of the rolled metal between the two pairs of rolls. In order to prevent the loop from falling sidewise, I erect upon the trough 1S the guide stakes 44, which are removably held in sockets 45 attached to the sides of the trough 18. v
